Silicone Flange Caps

Series: VFC

Silicone flange caps for stud & grounding area masking (600°F)

Reusable masking caps designed to protect studs, bolts, and surrounding circular areas during high-heat finishing processes. Ideal for masking studs or bolts and a circular area around them, typically for grounding area protection.

Our silicone flange caps eliminate the need for secondary washers by masking the circular area around the bolt, saving labor time in powder coating and e-coating lines.

Alternatively can be used as a plug: The area around a hole can then be masked by the flange. They have also been used successfully as an insulation for wire harnesses (by cutting off the rounded end).
